How loud should a wedding sound system be?
Quick answer
A wedding sound system should deliver clean, intelligible sound at 85–95 dB average with peaks around 100–105 dB, which is loud enough for dancing but allows conversation at tables. For most wedding venues (up to 200 guests), a pair of 12-inch powered speakers with a 15- or 18-inch subwoofer is sufficient.
The ideal loudness for a wedding balances energy for the dance floor with comfort for dining and mingling. Aim for an average SPL of 85–95 dB at the listening area, with peaks up to 100–105 dB for upbeat moments. This range ensures guests can still talk without shouting while the music feels immersive. Exceeding 110 dB risks hearing damage and guest complaints.
System sizing depends on venue size and guest count. For 100–200 guests in a typical hall or tent, two 12-inch powered speakers (e.g., SSOUNDS point-source systems) plus one 15- or 18-inch subwoofer provide ample headroom. For larger venues or outdoor weddings, consider adding a second sub or upgrading to a compact line array like SSOUNDS’ portable arrays for even coverage without hot spots.
Key factors: coverage pattern (90° x 60° is versatile), power (500–1000W RMS per side), and subwoofer extension (down to 35 Hz). Always set limiters and avoid clipping. Use a DSP or mixer with a graphic EQ to tame room resonances. For speeches, ensure the system can deliver clear vocals at 80–85 dB without feedback.
Key things to consider
- Target 85–95 dB average, 100–105 dB peaks for dance floor energy without overwhelming guests.
- For up to 200 guests: two 12-inch powered tops + one 15- or 18-inch subwoofer (500–1000W RMS each).
- Outdoor or larger venues may require additional subs or a compact line array for even coverage.
- Use a mixer with EQ and limiters to maintain clean sound and protect speakers.
- Prioritize vocal clarity for speeches: aim for 80–85 dB with minimal feedback.
